Anyone else who built their own trim/relay board know the value for the diode rectifiers used to protect the relay and trim switches from arcing the contacts? Or any on who used the Aircraft Extras or Ray Allen relay decks know what value they put in their decks? 

  

 I suspect a 1 amp by 50 volt should do. Circut draws less than an amp.

I built up my own0 trim/flap relay board for my 8A, no diodes.  The current draw is too0 small.

I built my own Trim/Flap controller board for my RV-9 and RV-10.  It uses all solid state MosFet so there is no moving parts to wear out.  I used 50 Amp Mosfet for the Flap motor so they don’t even get the least bit hot.  

     

Thank You
